Abstract (en)

[origin: US2014249044A1] The invention relates to cell-based methods for diversifying, expressing and selecting binding molecules, e.g., antibodies, and target molecules to which they bind, all of which are expressed in the same cell. The target molecule can be a member of a ligand binding pair comprising a cell-surface expressed ligand binding receptor molecule and its cognate ligand, which interact within the cell. The methods provide retaining either the antibody or its target in a cell organelle as the site of binding and interaction. By performance of the methods, the binding or non-binding of the antibody to its target molecule within the cell produces a cell phenotype that is detectable at the cell surface via high throughput assays, e.g., flow cytometry. The methods are particularly useful for generating, recovering and providing antibodies that have optimal target molecule binding properties or activities for potential therapeutic use. Methods for generating diversity in such antibodies are also provided.
